Sir David Attenborough, 92, digs the BBC and joins Netflix for a blockbuster series

Sir David Attenborough has warned that humans have become the "greatest threat" to the health of our planet.

The experienced facilitator called on people to "pay attention" as long as "there is still time" to save the natural world.

The BBC fighter, 92, has opted for the streaming of the giant Netflix for the blockbuster series to bring the world into action.

More than 600 crew members have recorded 3,500 days of shooting in 50 countries to create Our Planet – an "ambitious" eight-part series.

Sir David, who tells the program, said the show will "take viewers on a spectacular expedition that shows the beauty and fragility of our natural world."

In a speech to WWF's State of the Planet speech last night, he warned, "Today we have become the greatest threat to the health of our home, but we still have time to face the challenges we have created when we act now. We need the world to be attentive.

"Our planet brings together some of the best filmmakers and conservationists in the world, and I'm delighted to be helping make this important story accessible to millions of people worldwide."

Sir David, who has worked for the BBC for more than 60 years, has been advocating people to reduce the use of plastic in Blue Planet.

And his upcoming series Dynasties, which starts on Sunday at BBC One, warns that the animal kingdom is threatened for reasons of space.

Our Planet, a joint venture of the founders of Planet Earth, WWF and Netflix, will premiere on 5 April 2019 in more than 190 countries. Director Alastair Fothergill, behind the BBC's hit series "Planet Earth" and "Blue Planet Natural History," said the show was "the most ambitious venture so far."

He said, "We hope this will inspire and inspire hundreds of millions of people around the world to understand our planet and the environmental threat it faces as never before.

"By launching Netflix all over the world at the same time, this series will give people the opportunity to connect with the shared responsibility we all have. We are really all together. "

Colin Butfield, Executive Director of WWF UK and Executive Producer of Our Planet, added: "We are the first generation to know the full impact of our activities on our planet and the last to have the opportunity to do something about it do it.

"We are in a unique moment in our history where we have the opportunity to get things right and start the path to a better future.

"Our planet will present the wonders of our world at a critical time when we need global action for protection."
